@alansopro There is indeed a new fog client, though the old one is there as a just in case but probably has its own set of issues. Besides, I HIGHLY encourage all people to use the new client. It’s much faster and less taxing on the FOG Server. While the old client wasn’t overly rough (after its initial load up) it still had it’s own issues to think/worry about.

I’m using FOG v1.2.0 and I updated the Kernel to 4.6.4. I’m running a CentOS 6 x64.

Well the recommended action is to upgrade to 1.3.0-rc4 to get all of the latest hardware support, with support for also uefi firmware, gpt disks, NVMe disks, Windows 10 plus many other performance enhancements. If I haven’t sold you on the upgrade…

For FOG 1.2.0 stable the maximum version of the kernel you can use is anything less than 4.4. In your case you will want to use 4.1.2 and that should address the issue.
